DUMP-CAR.

Application filed September 11, 1912.

Z 1o all 107mm tt may concern Be it known that l, Bierman lVnnn BUI:- Nrrrr, a citizen of the United States ot America, residing` at the city oit' lllontreal, Province of Quebec, Dominion of Canada, have invented certain new and useful lmprovements in Dump-Gars; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates particularly to dump cars of the type disclosed in my United States Patent application Serial No. 655,253, filed Oct. 17th, 1911, and which resulted in Patent No. 1,081,430.

My invention consists in a hinge for hop per doors adapted to close to positions in approximately vertical planes, and comprises a pair ot' hinge members each oi which has a series of hinged knuckles,--the knuckles oi' both hinge members interdigitating and being kept in alinement by a pintle extending from end to end of the hinge, and mounted in bearings in hopper-end walls,-the hinge members being so relatively arranged that when the door is closed the edges proper of such hinge members contiguous to the knuckles will come into con tact, as shown in Fig. 1, thus preventing leakage of the finest mesh lading therethrough.

For full comprehension, however, of my invention reference must be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate the same parts, and wherein:

Figure 1 is a vertical sectional view of a dump car hopper taken on a line extending transversely relatively to the car; Fig. 2 illustrates aI dump ear door in elevation and provided with my invention; Fig. 3 is a detail sectional view taken on line A A Fig. 1 of one of the flanged ends of the door and the hopper in which it engages; Fig. 4: is a detail perspective View of a portion of the hopper floor member and one end wall; Fig. 5 is a detail perspective view of the clamp-` ing device; Fig. 6 is a detail elevation of the means for locking the door clamping means; and Fig. 7 is a detail sectional View of the means for mounting the hinge bar.

The hopper floor is indicated at b and the hopper end-plates at c, the l'loor extending from the center sill Z of the car to within close proximity ontl the vertical plane of the side sill e of the car thus placing the Specification of Letters Patent.

discharge opening approximately perpendicnlarly. The center sill (l and side sill c ot' the car constitute hopper sills. The dulnp door j is hinged to the floor member and its ends are flanged as at f/ and engage pockets g in the :front edges ci' the hopper ends while the tree side edge oil the door engages a 'flange s upon the side sill, and it is clamped in its shut position, after having been manually closed, by a rock-shaft t carrying a series et dogs J. This type of door :forms an extension of the floor oi the hopper and throws the lading a considerable distance laterally, which is an advantage in that it is thrown clear of the rails. lVith doors ol this type and applied in the manner described to hoppers through which granular commodities are discharged, while the tree edges are effectively closed against leakage by the clamping appliance described, the hinged edge has been heretofore a source ot trouble owing` to leakage due to wear, imperfect fitting, and, in some cases, inherent weakness unless constructed from extra heavy materials. In order to overcome these detects the hinge consists of a pair oli plates 'forming the door and floor member respectively and one edge of each plate is formed with hinge knuckles consisting ot' spaced tongues fm and a, respectively, struck l'rom sheet metal and curved to tubular Ylorrn or cast in that form, the knuckles of one plate being adapted to interdigitate with the knuckles ol' the other plate while they collectively form when alined in eil'ect a practically continuous tnbular hinge, the parts oi which are maintained in alinement and the hinge itself and through it the door are supported by a hinge bar 0 mounted in a socket p secured to the end plates ot' the hopper, and rigidly secured to the knuckles of the door by rivets u.

A hinge of the form described eiliectively prevents leakage between the door and hopper floor member, and. is strong and durable and of simple construction.

l do not herein claim the hinge construction as the same forms the subject-matter of a separate application to be subsequent-ly filed.

lVhat I claim is as follows ln a hopper lor dump cars, end plates, hopper sills at the opposite sides of the top thereof, an inclined floor member extending :from one oi said sills to within close proximity of the Vertical plane of the other of said sockets upon the end Walls of the hopper sills, a door for Closing the opening inelosed receiving and supporting the pintle. by the end plates, the floor, and the last In testimony whereof I have signed my mentioned sill; and a hinge, joining the door name to this specification in the presence of 5 and the floor menber, znc conlisting ola two Witnesses.
